Abstract
The invention discloses a kind of concrete tapered pile basis, be made up of several concrete tapered piles, concrete tapered pile comprises pile body and shoe, shoe two ends area is not etc., one end top little at area is provided with steel plate, top is wrapped up by steel plate completely, one end that area is large and pile body connect as one, at pile body outer wall, U-shaped reinforcing bar is evenly set, along cross-sectional uniformity, 2-4 group is set, U-shaped Bar Anchorage end is fixed in pile body, notch is towards pile body, longitudinally one group of U-shaped reinforcing bar is set every 0.5m-0.8m, and U-shaped reinforcing bar distance pile body top 0.3m, by the U-shaped reinforcing bar binding of stirrup by adjacent concrete tapered pile, adjacent concrete tapered pile is linked together, form concrete tapered pile basis.Shoe part of the present invention is halfpace type, effectively prevents inclination and the sinking of pile body, reduces site foundation treatment process, and construction is simple.
Description
Technical field
The invention belongs to the shallow layer soft soil foundation treatment technology of civil engineering, be specifically related to a kind of concrete tapered pile basis.
Background technology
In recent years; in view of pile foundation effectively can suppress sedimentation, controls differential settlement and can realize the advantage of high-quality, standardization and large-scale production, each side such as little, of many uses affected by environment; be widely used in deep mud and saturated soft clay foundation build building construction, it has broad application prospects in China.But existing pile foundation is all generally positioned by raft formula aperture plate (netted welded reinforcement), and it needs a large amount of steel, and construction cost is high; It needs to connect into entirety by the dowel of raft formula connection network and each stake block, and higher to the coherence request of the arrangement of each stake block, difficulty of construction is large; When pile body is settled, need the breakage of on-the-spot shallow layer soft soil being filled out to shoe when rubble or rammed subgrade prevent from pressing down pile body, working procedure is complicated.Therefore, be necessary that research one is both economical, the pile foundation that working procedure is easy again.
Summary of the invention
The object of the present invention is to provide a kind of concrete tapered pile basis, when solving existing pile foundation construction, the site operation processed existing for on-the-spot rubble is loaded down with trivial details, and construction period length waits confinement problems.
The technical solution realizing the object of the invention is: a kind of concrete tapered pile basis, be made up of several concrete tapered piles, concrete tapered pile comprises pile body and shoe, shoe two ends area is not etc., one end top little at area is provided with steel plate, top is wrapped up by steel plate completely, one end that area is large and pile body connect as one, at pile body outer wall, U-shaped reinforcing bar is evenly set, along cross-sectional uniformity, 2-4 group is set, U-shaped Bar Anchorage end is fixed in pile body, notch is towards pile body, longitudinally one group of U-shaped reinforcing bar is set every 0.5m-0.8m, and U-shaped reinforcing bar distance pile body top 0.3m, by the U-shaped reinforcing bar binding of stirrup by adjacent concrete tapered pile, adjacent concrete tapered pile is linked together, form concrete tapered pile basis.
Above-mentioned concrete tapered pile cross section is square or circular.
Above-mentioned U-shaped reinforcing bar often group is no less than 1.
Compared with prior art, its remarkable advantage: be connected to each other between (1) each centrum stake, forms Unified Global and effectively can resist local sedimentation in the present invention; (2) shoe part is halfpace type, effectively prevents inclination and the sinking of pile body; (3) reduce site foundation treatment process, construction is simple; (4) bottom shoe, stick steel disc, destroyed bottom shoe when pressing down to prevent pile body.
Accompanying drawing explanation

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
First is below that foursquare 3*3 tapered pile is described for cross section.
Composition graphs 1, Fig. 2 and Fig. 3, the present invention is a kind of concrete tapered pile basis, be made up of several concrete tapered piles 1, concrete tapered pile 1 comprises pile body 2 and shoe 3, pile body 2 cross section is the square of length of side 40cm, shoe 3 two ends area is not etc., the end section be connected with pile body 2 is the square of length of side 40cm, other end cross section is the square of length of side 10cm, and this end top that area is little is provided with steel plate 4, top is wrapped up by steel plate 4 completely, at pile body 2 outer wall, U-shaped reinforcing bar 5 is evenly set, be positioned at middle concrete tapered pile 1, along cross-sectional uniformity, 4 groups of U-shaped reinforcing bars 5 are set, be positioned at concrete tapered pile 1 on corner position and 2 groups of adjacent U-shaped reinforcing bars 5 are set respectively along cross section, remaining four concrete tapered pile 1 arranges 3 groups of adjacent U-shaped reinforcing bars 5 respectively along cross section, above-mentioned U-shaped reinforcing bar 5 often group has 1 reinforcing bar, U-shaped reinforcing bar 5 anchored end is fixed in pile body 2, notch is towards pile body 2, U-shaped reinforcing bar 5 is apart from pile body top 0.3m, longitudinally one group of U-shaped reinforcing bar 5 is set every 0.6m.
Specific construction step is as follows:
Step 1: be prefabricated in the factory taper concrete pile 1 be transported to scene.
Step 2: carry out simple basement process at the construction field (site), throwing rubble.
Step 3: taper concrete pile 1 is placed in precalculated position.
Step 4: press down taper concrete pile 1 and make steel plate 4 half bottom shoe 3 be absorbed in the soil body.
Step 5: with stirrup 6 by U-shaped reinforcing bar 5 colligation of adjacent concrete tapered pile 1.
Step 6: filling 40-50mm Stone between concrete tapered pile 1 compacting.
Step 7: build C25 concrete seven and make each pile body form an entirety between concrete tapered pile 1.
